    Study Notes

    Module Two: The Impact of Science on Society

    • This module examines various ways science impacts modern society, including energy production, health, information technology, and biological/biotechnological research.
    • Daily activities rely on energy, directly or indirectly.
    • Industries within the Caribbean heavily depend on energy.
    • High energy costs affect regional economies and the physical environment.
    • Good health and food supply are fundamental to society’s productivity and well-being.
    • Current research pushes the boundaries of knowledge concerning life, its conditions, and management.
    • Ethical issues arising from this research must be carefully considered.
    • Information technology significantly influences societal organization and communication.
    • The Caribbean is no exception; daily interaction with the rest of the world through the internet, cell phones, and cable TV is commonplace.
    • Understanding the key principles of information technology is important.

    Unit 1: Basic Scientific Concepts

    • Matter is composed of small particles, which can be atoms, molecules, or ions.
    • The atom is the fundamental unit of matter.
    • Atoms are made up of electrons, protons and neutrons.
    • Electrons have a negative charge, protons are positive and neutrons have no charge.
    • Atoms bond together to form molecules. The way atoms bond, how many atoms are involved, and the resulting arrangement in molecules determine the properties of the compound.
    • Nuclear reactions release significant energy. The energy can be harnessed in controlled ways, e.g. nuclear power plants or in uncontrolled ways, e.g. atomic bombs.

    Unit 2: Energy Production and Use

    • Energy is the ability to do work. It exists in various forms, e.g., kinetic, potential, thermal, and nuclear.
    • Kinetic energy describes a body's energy due to its speed of motion.
    • Potential energy is a body's stored energy.
    • Thermal energy is related to heat.
    • Nuclear energy is related to the atomic nucleus.
    • Non-renewable energy sources include crude oil, natural gas, and coal. These are finite resources and their use has implications for the future.
    • Renewable sources include the sun, wind, and ocean tides. These are continuously replenished.

    Unit 2: Energy Production and Use (Continued)

    • Coal, a fossil fuel, is obtained from plant materials compressed deep in the earth over time. Coal is used to generate electricity and for other applications.
    • Refining crude oil separates simpler mixtures from complex hydrocarbon mixtures to produce usable products (e.g., gasoline, kerosene, and heating oil). These products differ based from their boiling points.
    • Large quantities of natural gas are found in many parts of the world. It is an important alternative energy source and it can be stored as liquid form as a mean to transport the energy to places in demand.

    Unit 2: Energy Production and Use (Continued)

    • Fossil fuels, while useful, produce pollutants like carbon dioxide and sulfur dioxide, and are therefore harming the atmosphere.
    • Conserving energy and exploring alternative energy sources are paramount to the sustainable development of Caribbean nations.
    • Solar power, wind power, and ocean thermal energy conversion are examples of renewable energy sources.

    Unit 3, Unit 4, Unit 5, Unit 6 (and others)

    • The remaining unit summaries in the document are not provided, this section can be completed based on the given information.
